php - Verify if an email address is active -


I have tried to check that the email address is present and alive as a SMTP server, but I get the answer Is as accurate as possible.

The only way to prove that an email is alive is email confirmation after process registration. You have to send a link to your newly registered / registered user about your email confirmation. For example: A new user aaa@bbb.ccc with the email is registered and has been saved in the database with "as23kja45" in his email id. "You can call it yoursite.com/confirmation.php?id=as23kja45 < / strong> link after clicking on this link you can read the ID in the absolute value, check it in the database, it exists, if true => you have an email address alive

Before sending this kind of link to you email satisfies email address To prove the form, email must be checked by some email verifier.
